like 2 scoops whey, a few nuts, and sum PB
that really does wut a gainer does?

Its better than a gainer because your getting quality calories not just 4 scoops of maltodextrin. If you want just calories and don't care about getting fat, I would recommend Muscle Juice by Ultimate Nutrition.

Whey, oats, and pb will be your best gainer that is good for you too. Not protein rich, but another good gainer is a simple pb&j sandwich. Use whole wheat brean, sugar free jelly, and natty PB.

Also, don't say you're eating "a lot" without disclosing how much "a lot" is. 7 or 8 large meals (800cals each) a day is a lot. "stuffing your face during dinner time" is not how you gain muscle - continual measured eating throughout the day is.

I'm not saying you need to eat 800cals 8 times a day, I'm just giving you a frame of reference - takes a lot of cals to fuel hypertrophy.

If I was to gain mass how many of those protein shakes with all those healthy ingredients would I take in a day?

Like I said before, you really need to do some research on nutrition and diets. There isn't a set number of shakes you need a day. You have to find out your baseline caloric intake to maintain and adjust from there. Typically in 500cal increments as needed. Gainers in my mind are overpriced. Hell, just buy a tub of carbogain from NOW and add it to your shakes if you want even more calories. There is nothing special about gainers in general. The only one that I find solid is MHP "Up Your Mass" as it uses ground oats in it, but its way to expensive. Get a coffee grinder and grind your own and scoop in a shake as needed.

Best natty pb i've found is Skippy Natural. No oil on the top, no need to stir, and tastes damn good.
